RE: Bar Graph Voltage Monitors - Plan repository?

["Dave Mumert" <dmumert@telusplanet.net>]

Hi All;

Check out www.capilano.com for DesignWorks Lite. It's a FREE schematic
drawing software.  I have used it and it seems to be OK.  A fairly complex
drawing uses about 200K and zips down to 50K.

Maybe we could pick a standard package so we can share 'components' as well
as drawings.

I think you guys hit on a great idea.  I have thoughts of building battery
monitor also !  Like some one else said, one readout with electronics to go
through the pack ( you could even do one cell at a time ) and alert you
before you leave the house.  When I worked for Honeywell Solid State in the
sensors engineering lab, we used solid state switches that would switch
different voltage levels from separate inputs into a hi resolution volt
meter to take precision readings on different parts under test.  Can't
remember the part numbers but I'll try and find it.

While you at it, why not create a small data base for each EV system.
One for motors and controllers, heating systems, battery chargers as well as
instrumentation.  With all the talent on the EV list we could set basic
standards so each person who wants to convert doesn't have to re-invent the
wheel.

I'll help !

Cheers !
